At the time of charging, charging is started by attaching the charging connector 3 to the power supply inlet V1 of the electric vehicle V and pressing a charging start button or the like provided on the charging stand 1.

　また、充電ケーブル２は、充電スタンド１の近くに駐車した電気自動車Ｖの給電インレットＶ１まで達するよう、十分な長さを有する。例えば、１０ｍ前後の長さが一般的である。そして、非充電時には、充電ケーブル２が邪魔にならないように、例えば、充電ケーブル２を渦巻状に巻回することができる。また、充電コネクタ３は、充電スタンド１の筐体の正面に設けられた所定の部位に格納される。 Further, the charging cable 2 has a sufficient length so as to reach the power supply inlet V1 of the electric vehicle V parked near the charging stand 1. For example, a length of about 10 m is common. And at the time of non-charging, the charging cable 2 can be wound, for example in a spiral shape so that the charging cable 2 does not get in the way. The charging connector 3 is stored in a predetermined part provided on the front surface of the casing of the charging stand 1.

　本形態の中間把持具４は、充電スタンド１より伸びる充電ケーブル２に装着されるものである。そして、充電ケーブル２により貫通されるように形成され、かつ、前記充電スタンド１に鉤状に設けられたフック５に掛止される筒部４１を備える。さらに、筒部４１より延在して充電作業者に把持されるグリップ部４２を備える。 The intermediate gripping tool 4 of this embodiment is attached to the charging cable 2 extending from the charging stand 1. And it is provided with the cylinder part 41 which is formed so that it may penetrate by the charging cable 2, and is hooked by the hook 5 provided in the said charging stand 1 in hook shape. Furthermore, the grip part 42 extended from the cylinder part 41 and hold | gripped by the charging operator is provided.

　中間把持具４は、例えば、プラスチック等の絶縁材料から構成されるものとすることができる。そして、例えば、図２に示すように充電ケーブル２の軸方向に対して左右に二つ割りに形成された部材を合わせたものとすることができる。すなわち、図２及び図３に示すように、筒部４１が充電ケーブル２を被覆して貫通させるように二つ割りにされた部材を、ボルト４４及びナット４５を用いて固定することができる。このようにして、中間把持具４を充電ケーブル２に装着することができる。もちろん、このような態様に限定されず、中間把持具４を充電ケーブル２に装着する際には、従前公知の態様で装着することができる。 The intermediate gripping tool 4 can be made of an insulating material such as plastic, for example. Then, for example, as shown in FIG. 2, it is possible to combine the members that are divided in the left and right with respect to the axial direction of the charging cable 2. That is, as shown in FIGS. 2 and 3, the member divided in half so that the cylindrical portion 41 covers and penetrates the charging cable 2 can be fixed using the bolt 44 and the nut 45. In this way, the intermediate gripping tool 4 can be attached to the charging cable 2. Of course, the present invention is not limited to such a mode, and when the intermediate gripping tool 4 is mounted on the charging cable 2, it can be mounted in a conventionally known mode.

　なお、中間把持具４を充電ケーブル２に装着する際、筒部４１の内径及び充電ケーブル２の外径の関係を考慮して、ボルト４４とナット４５との間の締め付け具合を調節することができる。ボルト４４とナット４５との間の締付力が大きくなるほど、筒部４１と充電ケーブル２との間に働く押付力が大きくなる。なお、当該押付力が大きくなるにつれて、筒部４１と充電ケーブル２との間に働く摩擦力も大きくなる。筒部４１と充電ケーブル２との間に摩擦力（押付力）が働くと、充電ケーブル２の筒部４１と接触する部分が変形する。このような変形が生ずるように、充電ケーブル２に中間把持具４が装着されることにより、充電ケーブル２においては、当該摩擦力（押付力）が働いて変形された部分と摩擦力（押付力）が働かず変形されていない部分とが存在することになる。充電ケーブル２の軸方向への筒部４１の移動により、当該変形されていない部分を変形させることは困難である。したがって、充電ケーブル２の軸方向への筒部４１の移動が防止される。このような状態に至らしめる摩擦力の閾値は、筒部４１及び充電ケーブル２の表面の弾性や摩擦係数などの、双方の表面特性に依存する。すなわち、筒部４１及び充電ケーブル２の表面特性を考慮した上、ボルト４４とナット４５との間の締付力を決定することができる。このようにして筒部４１を充電ケーブル２に装着した場合、充電ケーブル２の軸方向への筒部４１の移動を防止することができる。さらに、充電ケーブル２の軸方向への筒部４１の移動が規制された状態であっても、筒部４１が充電ケーブル２の軸周りに回転可能となっていることが好ましい。図３の矢印Ｒ方向で示すように、筒部４１が回転可能とされていることにより、フック５に対して充電スタンド１と逆側に向けてグリップ部４２を傾斜させた状態で、中間把持具４をフック５に掛止することができる。その結果、次に充電操作を行う際に充電作業者がグリップ部４２を容易に把持することができる。このように、筒部４１を回転可能にするためには、前述と同様に筒部４１及び充電ケーブル２の表面特性を考慮した上で、ボルト４４とナット４５との間の締付力を調整すればよい。 When attaching the intermediate gripping tool 4 to the charging cable 2, it is possible to adjust the tightening degree between the bolt 44 and the nut 45 in consideration of the relationship between the inner diameter of the cylindrical portion 41 and the outer diameter of the charging cable 2. it can. As the tightening force between the bolt 44 and the nut 45 increases, the pressing force acting between the tube portion 41 and the charging cable 2 increases. Note that, as the pressing force increases, the frictional force acting between the tube portion 41 and the charging cable 2 also increases. When a frictional force (pressing force) acts between the tube portion 41 and the charging cable 2, the portion that contacts the tube portion 41 of the charging cable 2 is deformed. By attaching the intermediate gripping tool 4 to the charging cable 2 so as to cause such deformation, in the charging cable 2, the frictional force (pressing force) and the portion deformed by the frictional force (pressing force) work. ) Does not work and there are parts that are not deformed. It is difficult to deform the undeformed portion by moving the cylinder portion 41 in the axial direction of the charging cable 2. Therefore, the movement of the cylinder part 41 in the axial direction of the charging cable 2 is prevented. The threshold value of the frictional force that leads to such a state depends on both surface characteristics such as the elasticity of the surface of the cylindrical portion 41 and the charging cable 2 and the friction coefficient. That is, the tightening force between the bolt 44 and the nut 45 can be determined in consideration of the surface characteristics of the cylinder portion 41 and the charging cable 2. Thus, when the cylinder part 41 is attached to the charging cable 2, the movement of the cylinder part 41 in the axial direction of the charging cable 2 can be prevented. Furthermore, it is preferable that the cylinder part 41 is rotatable around the axis of the charging cable 2 even when the movement of the cylinder part 41 in the axial direction of the charging cable 2 is restricted. As shown in the direction of arrow R in FIG. 3, the cylindrical portion 41 is rotatable, so that the gripping portion 42 is inclined toward the opposite side of the charging stand 1 with respect to the hook 5 and the intermediate gripping is performed. The tool 4 can be hooked on the hook 5. As a result, the charging operator can easily grip the grip portion 42 when performing the charging operation next time. As described above, in order to make the tube portion 41 rotatable, the tightening force between the bolt 44 and the nut 45 is adjusted in consideration of the surface characteristics of the tube portion 41 and the charging cable 2 as described above. do it.

　筒部４１の外周面において、筒部４１をフック５に掛止したときにフック５に係合される環状凹凸部４３が備えられていることが好ましい。なお、「環状凹凸」とは、筒部の表面に形成された凹凸であって、当該凹凸が筒部の軸方向に形成されているとともに、凹部と凸部とがそれぞれ筒部の周方向に沿って連設されているような形状を意味する。この環状凹凸部４３により、筒部４１がフック５に対して横滑りすることが防止され、筒部４１を安定させることができる。さらに、筒部４１において、環状凹凸部を複数備えるものとしてもよい。すなわち、当該複数の環状凹凸部が、互いに間隔をもって充電スタンドに設けられた複数本のフックにそれぞれ係合するように配置されることが好ましい。このようにすることで、筒部４１を更に安定させることができる。図２では、フック５を１本のみ設けた例を示しており、図４では、互いに間隔をもった２本のフック５を配置した例を示している。なお、図４では、フック５，５それぞれに係合する複数の環状凹凸部４３の例を示している。もちろん、２本に限られず、２本以上の複数本としてもよい。 It is preferable that an annular concavo-convex portion 43 that is engaged with the hook 5 when the cylindrical portion 41 is hooked on the hook 5 is provided on the outer peripheral surface of the cylindrical portion 41. The “annular irregularities” are irregularities formed on the surface of the cylindrical portion, and the irregularities are formed in the axial direction of the cylindrical portion, and the concave portion and the convex portion are respectively in the circumferential direction of the cylindrical portion. It means the shape that is connected along. The annular concavo-convex portion 43 prevents the cylindrical portion 41 from sliding to the hook 5 and can stabilize the cylindrical portion 41. Furthermore, in the cylinder part 41, it is good also as a thing provided with multiple annular uneven | corrugated | grooved parts. That is, it is preferable that the plurality of annular concavo-convex portions are arranged so as to engage with a plurality of hooks provided on the charging stand at intervals. By doing in this way, the cylinder part 41 can be stabilized further. FIG. 2 shows an example in which only one hook 5 is provided, and FIG. 4 shows an example in which two hooks 5 spaced apart from each other are arranged. FIG. 4 shows an example of a plurality of annular concavo-convex portions 43 that engage with the hooks 5 and 5 respectively. Of course, the number is not limited to two and may be two or more.

　グリップ部４２は、図２に示すように、筒部４１をフック５に掛止した状態で充電作業者が把持できる形状とされている。図２に示す例では、筒部４１の両端からそれぞれ上部へ延在して繋がる形状とされているが、このような形状に限定されない。すなわち、充電作業者が把持でき、かつ、フックに掛止できるような形状であればよく、例えば、筒部４１の一方端部から上部へ延在する片持ち形状であってもよい。 As shown in FIG. 2, the grip portion 42 has a shape that can be gripped by a charging worker in a state where the tube portion 41 is hooked on the hook 5. In the example illustrated in FIG. 2, the shape extends from the both ends of the tubular portion 41 to the upper portion, but is not limited thereto. That is, the shape may be a shape that can be held by the charging worker and can be hooked on the hook. For example, the shape may be a cantilever shape that extends upward from one end of the cylindrical portion 41.

　次いで、充電操作を説明する。非充電時は、図５に示すように、充電ケーブル２の先端に設けられた充電コネクタ３を充電スタンド１の正面に設けられた所定部位に収納することができる。その際、充電ケーブル２に装着した中間把持具４の筒部４１を充電スタンド１の側面に設けられたフック５に掛止し、充電ケーブル２を渦巻状に巻回した状態とすることができる。 Next, the charging operation will be described. At the time of non-charging, as shown in FIG. 5, the charging connector 3 provided at the tip of the charging cable 2 can be stored in a predetermined part provided in the front of the charging stand 1. At that time, the tubular portion 41 of the intermediate gripping tool 4 attached to the charging cable 2 can be hooked on the hook 5 provided on the side surface of the charging stand 1 so that the charging cable 2 is wound in a spiral shape. .

　充電を開始する場合には、片手で充電コネクタ３を所定部位から取り外し、もう一方の手で中間把持具４のグリップ部４２を把持して筒部４１をフック５から取り外すことができる。これにより、充電作業者は充電ケーブルの先端を片手で把持すると共に、充電ケーブルをもう一方の手で把持することができる。 When charging is started, the charging connector 3 can be detached from a predetermined portion with one hand, the grip portion 42 of the intermediate gripping tool 4 can be gripped with the other hand, and the tube portion 41 can be detached from the hook 5. Thereby, the charging worker can hold the tip of the charging cable with one hand and the charging cable with the other hand.

　上述したとおり、高圧で大電力が流れる充電ケーブル２には、それに応じた耐電圧性と強度を兼ね備えることが要求される。そのため、そのような要求を満たす充電ケーブルは、太く、硬く、しかも重いケーブルになる傾向がある。一方、本形態の中間把持具４によれば、充電ケーブル２を能率的に両手で把持することができる。したがって、充電コネクタ３を電気自動車Ｖの給電インレットＶ１に装着する操作が容易になる。また、充電ケーブル２が渦巻状に巻回された場合であっても、中間把持具４により充電ケーブル２を保持できるので、その捩れを容易に解消することができる。 As described above, the charging cable 2 through which high power flows at a high voltage is required to have voltage resistance and strength corresponding to the charging cable 2. For this reason, charging cables that satisfy such requirements tend to be thick, hard, and heavy cables. On the other hand, according to the intermediate gripping tool 4 of the present embodiment, the charging cable 2 can be efficiently gripped with both hands. Therefore, the operation of attaching the charging connector 3 to the power supply inlet V1 of the electric vehicle V becomes easy. Further, even when the charging cable 2 is wound in a spiral shape, the charging cable 2 can be held by the intermediate gripping tool 4, so that the twist can be easily eliminated.

　充電ケーブル２を両手で把持したら、充電作業者自身が回転するなどして充電ケーブル２の捩れを解消しながら引き伸ばし、電気自動車Ｖの給電インレットＶ１に充電コネクタ３を装着する。そして、その後に中間把持具４を手から離し、充電スタンド１に設けられた充電スタートボタンを押して充電処理を開始する。 When the charging cable 2 is grasped with both hands, the charging operator himself / herself rotates and extends while eliminating the twisting of the charging cable 2, and the charging connector 3 is attached to the feeding inlet V 1 of the electric vehicle V. After that, the intermediate gripping tool 4 is released from the hand, and the charging start button provided on the charging stand 1 is pressed to start the charging process.

　充電処理が終了したら、充電作業者は、片手で充電コネクタ３を把持するとともに、もう一方の手で中間把持具４のグリップ部４２を把持する。そして、充電コネクタ３を給電インレットＶ１から取り外した後、充電ケーブル２を再び渦巻状に巻回しながら充電コネクタ３を充電スタンド１の所定部位に収納し、中間把持具４の筒部４１をフック５に掛止する。 When the charging process is completed, the charging operator holds the charging connector 3 with one hand and holds the grip portion 42 of the intermediate holding tool 4 with the other hand. Then, after the charging connector 3 is removed from the power supply inlet V1, the charging connector 3 is housed in a predetermined portion of the charging stand 1 while the charging cable 2 is wound again in a spiral shape, and the cylindrical portion 41 of the intermediate gripping tool 4 is hooked 5 Hang on.

　このように、本形態に係る中間把持具４を装着することにより、太く、硬く、しかも重い充電ケーブル２であっても、その取扱い作業性及び操作性が向上し、非力な充電作業者であっても容易に充電操作を実行することができる。また、非充電時には、充電ケーブル２を渦巻状に巻回して中間把持具４の筒部４１をフック５に掛止できるため、充電ケーブル２が地面に着いて汚れることも防止することができる。 As described above, by attaching the intermediate gripping tool 4 according to the present embodiment, even if the charging cable 2 is thick, hard, and heavy, its handling workability and operability are improved, and it is a weak charging worker. However, the charging operation can be easily performed. Further, at the time of non-charging, the charging cable 2 can be wound in a spiral shape so that the cylindrical portion 41 of the intermediate gripping tool 4 can be hooked on the hook 5, so that it is possible to prevent the charging cable 2 from getting on the ground and becoming dirty.

　また、本形態に係る中間把持具４の筒部４１において、筒部４１をフック５に掛止したときにフック５に係合される環状凹凸部４３を備えている。そのため、非充電時に充電ケーブル２に対して何らかの外力が作用してもフック５から容易に脱落することを防止することができる。すなわち、中間把持具４をフック５に掛止する際の安定性が向上する。特に、図４に示すように、複数の環状凹凸部４３，４３が、互いに間隔をもって充電スタンドに設けられた複数本のフック５，５にそれぞれ係合するように配置されることで、その安定性がより顕著になる。 Further, the cylindrical portion 41 of the intermediate gripping tool 4 according to the present embodiment includes an annular uneven portion 43 that is engaged with the hook 5 when the cylindrical portion 41 is hooked on the hook 5. Therefore, even if some external force acts on the charging cable 2 during non-charging, it can be prevented from easily falling off the hook 5. That is, the stability when the intermediate gripping tool 4 is hooked on the hook 5 is improved. In particular, as shown in FIG. 4, the plurality of annular concavo-convex portions 43, 43 are arranged so as to be engaged with the plurality of hooks 5, 5 provided on the charging stand with a space between each other. Sex becomes more remarkable.

　また、本形態に係る中間把持具４の筒部４１は、ボルト４４及びナット４５の締め付け具合を調節することにより、充電ケーブル２の軸周りに回転可能となっている。そのため、中間把持具４をフック５に掛止する際に、筒部４１を図３の矢印Ｒの右側に回転させておくことができる。このようにすれば、次に充電操作を行う際に充電作業者がグリップ部４２を容易に把持することができる。 Further, the cylindrical portion 41 of the intermediate gripping tool 4 according to this embodiment can be rotated around the axis of the charging cable 2 by adjusting the tightening degree of the bolt 44 and the nut 45. Therefore, when the intermediate gripping tool 4 is hooked on the hook 5, the cylindrical portion 41 can be rotated to the right side of the arrow R in FIG. In this way, the charging operator can easily grip the grip portion 42 when performing the charging operation next time.
